Telling people you are good at something until someone agrees with you, which in part you deny that you are good at all.

Shogo: So you're all "I got the music in me" 'til someone agrees with you? Then it's all..I'm gonna call it false modesty. Can't have it both ways...I've heard you play. Stick with, "I got the music in me." It's a better fit. Confidence, Shuya, confidence.
